Chest rig Wosport Tactical Micro Chest Rig MK4 — Ranger Green

The Wosport Tactical Micro Chest Rig MK4 is a compact, modular load-bearing system designed for those working in confined spaces or needing a lightweight layer over a plate carrier. The design takes clear inspiration from the Spiritus Systems Micro Fight Chassis MK4 and weighs 590 g empty, providing genuine carrying capacity without adding bulk to the torso.

The central body is lined with velcro on the inside of both compartments, so the layout of internal modules adapts to whatever magazines you are running: the main compartment holds up to 6 × 5.56 magazines or up to 4 × 7.62 magazines, with the option to mix rifle and pistol magazines in the same space. The rear velcro panel lets you attach additional accessories — a pouch, side radio pockets — or mount the entire rig directly onto a plate carrier with a velcro rear surface, removing the need to wear two separate systems.

The integrated H-harness features MOLLE webbing across the upper front, useful for attaching a PTT or other accessories without eating into magazine space. One trade-off to keep in mind: internal retention relies on velcro and the included inserts, not on hard retention or active closure elastics. The system is very quick to configure and to reload, but on rough terrain or during high-intensity movement it is worth considering whether to add a supplementary elastic insert for lighter magazines.

Key points

• Compatible with plate carriers featuring a rear velcro surface: worn as a single system with no additional harness required.
• MOLLE surface on the upper chest allows a PTT or accessories to be mounted without taking space from the magazine compartment.
• Main compartment configurable for 5.56, 7.62 or mixed rifle-pistol combinations via the included interchangeable inserts.
• Empty weight of 590 g is modest relative to the actual load capacity.
• Velcro-based internal retention: maximum configuration flexibility, with fast extraction and reloading without any release catches to operate.
